V DINING-TABLE SERVICE-INDICATOR.

To all whom it may concern:

Be it known that 1, Ennnsr W. WHITE, a citizen of the United States, and residing at Milford, in the county of Clermont and State of Ohio, have invented a new and useful Improvement in Dining-Table Service-Indicators, of which the following specification is a full disclosure. My invention relates to a service indicator for dining-room tables, providing a silent signal for an attendant or waiter that his services are requested by a guest at a particular table.

v It is an object of the invention to provide a small, ornatedevice, as a dining-table fixture or setting, extensible into a staff for attracting the attention of the attendant or waiter, indicating that a guest at the table is calling for his services.

Another object is to provide a construction of device for the purposes indicated as a post-like structure, which will be neat in appearance, simple in construction and operation, and which may be locked in a telescoped or compressed position, providing an arrangement of telescopic sections springpressed for rendering the sections as a unit automatically extensible, and means for cushioningthe sections at their limits of extensibility and providing for rigidity of the structure in its extended position.

An additionalobj set is to provide a, simple means for the attaching. and positioning of the cooperative springs. Additional objects and certain advantages will be set forth in the. description and special reference is made tothe drawings,

forming a. part of this specification, in which:

. Figure 1 isa vertical sectional view of the device in its extended position.

N Fig. 2 is a similar view in a depressed and locked position.

Fig. 3 is an enlarged fragmentary detail of one of the centering and attachment plugs, with the springs attached thereto.

Fig. 4: is a plan view of the plug shown in Fig.3. 7 Referring to the drawings, 1 designates a base bored centrally for the reception of the lower tube section 2, of a telescopic column or post composed of additional sections 3, 4. The lower end of the section 2 is closed by Specification of Letters Patent.

Application filed. June 8, 1920. Serial No. 387,419.

a disk 5, held in position by across-pin 6, I

of larger internal diameter than the externa l diameter of the section 3 and is annuand guide the said section 3. A circular centering and attachment plug 10 is he tened within the lower end of the section 3,

the same being composed of a disk portion 11, acting to center and guide the section 3 in its telescopic movement within the section 2 and to form a seat for a cushion spring, hereinafter described, and annularly interposed between the sections 2', 3. The plug 10 is secured within the end of the tube 3 by a cross pin 13 extending'through the tube section and plug. i

The construction of all plugs 10 is similar, as well as their placement at the lowerend of each telescopic section of'each of the sections comprised in the unit, and, therefore, the description of one is regarded as sufli cient. V An opening 1d is provided in the disk portion "11 of the plug 10 and openings 15, 16, are drilled in'the -plug, the"opening 16 receiving the upper terminal of the spring 8, and the openings. 14, 15, receiving respectively the lower end of a cushion spring 19, and the lower end of the expansion spring 20, of the section? Centrally'ofthe disk portion of the plug 10, depends a stop-pin 21,- designed to limit the downward movement ofthesection 3 by contact with the disk 5. ,A second plug is fitted within the lower end of the sections, the same being similar in construction and function tothe plug previously described, for the lower end within a housing at the top of the section 60 larly contracted as at 9 to loosely engage to lock the sections of the telescopic display column in their compressed position, as shown in Fig. 2.

The relative expansion and contraction sections of the springs 8 and 19 are such that the springs 19 act to arrest the movement of each section at a position whichwill prevent the lateral flexing or bending of the column at or near the extremities of thesections. and thus insure. the rigidity of the column. The cushioning springs counteract the expelled force of the expansion springs at the extended limits of the sections relieving the device of any tilting or upsetting jars from the rapidmovement of the sections when released from their depressed telescopic posi tion, and therefore tend to stabilize the device in its extended tornw.

Having described my invention, I claim:

1. In a telescopic display column, a tubular base section, a second tubular section telescopically mounted within said base section, expansion means within said base section for extending'the said second telescopic section, and means for limiting the extensive movem nt of the said second section, the said'ineans comprising a cushion spring carried by the said second section and surrounding the same, and abuttingly engag ing the said base section to retard and limit the extensive movement of the expansion means within the said base section.

2. In a telescopic display column, a tubular base section, a second tubular telescopic section arranged for extensible movement within said base section, a third tubular telescopic section arranged for extensible movement within said second section, expansion means within the base section and within the said second'section, and cushion means placed respectively between the base section and the second section, and between the second section and the said third section, the said cushion means acting-to -retard and limit the thrust of the said expan sion means within the said base and second section. v r r I 3. In a telescopic display, column, a tubular base section, a second tubular telescopic section arranged for extensible movement within said; base section,.a thirdtubular telescopic section arranged, for extensible I movement within said second section, expansion. means within the base section and with.- in. the said second section, cushion means placed respectively between the base sec tion and the second section, and between the second section and the said third section, the said cushion means acting to retard and limit the thrust of the said expansion means 1,eee,ess

within the said base and second section, and means for locking the said second and third sections in a depressed position.

l. In a telescopic display column, a tubular base section, a second tubular telescopic section arranged for extensible movement within said base section, a third tubular telescopic section arranged for extensible movement within said second'section, ex pansion means within the base section and within the said second section, cushion means placed respectively between the base section and the second section, and between second section and the said third section, the said cushion means acting to retard and limi the thrust of the said expansion means within the said base and second section, means for locking the said second and third sections in a depressed position, the said means consisting of a latch plate mounted at the top of the third section, and latch means cooperating therewith, the said latch means being placed at the top of the said base section.

5. in a device of the class described, a plurality of tubular telescopic sections telescopically and extensibly united, one section constituting a base section for supporting the structure, expansion means within saidv sections for automatically extending the same, means for limiting the extension of said sections to positions of maximum rigidity, the said means comprising a disk-like plug fastened in the lower end of each telescopic section, springs above and below the said plug and abutting the same, and cushsprii surrounding the lower portion cit said sections, the same abutting the said plug and theupper contracted portions of each telescopic section. I p I 6 A dining-table service indicator comextensible post-like structureoi plurality of sections telescopically united, base supporting said sections ina vertical lane, a spring housed within one section nl engaged with a second section for autoatically extending said second section,'and

spring between said sections for contracthe ex elled force of said first-named at the limit of extended movement of saic. second section, andmeans for locksaid sections in their depressed position one within the other. V V
